    On our rental equipment to be used inside we would spec out to have a catalytic converter to reduce the amount of Co being put out. Or we would add one to the stack.

    Get ready for fun, Big Orange is starting to push for vfd’s to run the blower and maintain a precise static pressure on the building.

    And it’s only precise when the building is used as designed. Most of them open the doors enough that the thing runs at 100% all the time. It’s especially nice for buildings that have multiple exhaust fans that may not run at the same time, then the vfd will ramp down as fans shut off.

    I can’t imagine it would be worth the money in most of what we do here, restaurants etc. when your just making up the air for a specific hood can. All of them we did were in some sort of industrial setting like factories or large fabrication shops with multiple machines and welding tables that had exhaust fans.

    I've got one like that now.

    I shut it down and the they restarted it, said it's been that way for years and they just throttle it with the shutoff cock based on how cold it is outside. :mrbill:

    Best part is, it's a box factory full of paper and cardboard dust.

    I fully expect to see the place burning down on the news one morning.

    direct fired MUAs - in the us you are allowed to run the discharge to a max of 75° in Canada we have a lower allowable Co2 levels so we can only run to 70°f I think that's 1200 ppm vs 1500 ppm

    Ive drilled out the orifices ( engair) you have to be careful not to drill out LARGER than originally sized or you will over fire the mua inadvertently

    Lol. Not saying you're incorrect, but I've seen them cranked up to 150 with the paint burned off the outside and nobody bats an eye.

    I did an LP to natural conversion on one years ago. Aluminum burner, crawled in there with the correct size bit and drilled out a lot of holes. Took a while.

    Couldn’t just run it with 10” manifold pressure on natural gas? Lol

    I worked on one last winter. I don’t know anything about it. It was cold outside. The owner has poor English. It worked perfect the whole time I was there.
